It might seem shocking to some, but there is a very vocal crowd who passionately believe that helmets don’t prevent head injuries. In fact, some even go so far as to say that they increase their likelihood because drivers give helmeted cyclists more “space.” Others argue that a helmet makes it more likely that you’ll whack your head on a branch or a side view mirror because it makes your head larger.

If these arguments sound a little ridiculous, that’s because they are. The website Bicycle Helmet Myths and Facts does a fantastic job of aggregating these myths and then showing how faulty their logic is. Check it out here.
